Patented May-31,

Application filed November 19, 1969. $erial No. 527,284.

To all whom it may concern:

have invented a certain ncw and useful Improvement in Push-Button Switches, of which the following is a specification.

My invention relates to electrical switches and particularly to push button switches, the object of my invention being to provide an inexpensive yet eilicient switch adapted for any use but particularly intended for automobiles and the like when a very small switch is desirable.

In the accompanying drawings, Figure l is a vertical longitudinal section on the line 1-1, Fig. 2; Figs. 2 and 3 are transverse vertical sections on the lines 2-2 and 3-3 Fig. 1 respectively; Fig. 4 is a partial horizontal section showing the rock lever partly operated; and Fig. 5 is a perspective of the box shell.

Describing my invention with reference to the embodiment thereof, illustrated in a flush switch, it comprises an insulating base A carrying on its lower. face the binding screws 10 and 11 through which the current is transmitted to the spring terminals 12 and 13 within the casing. The switch. member 14 is carried by the rock lever 15 pivoted to the standard 16 and is brought into and out of contact with the terminals 12 and 13 through the oscillation of the lever 15 by means of push buttons 17 and 18 pivoted I to the latter. top lugs 19 and 20 on the lever 15 limits its oscillation byahutting against the base and. insures the proper positioning of the contact member ll.

The standard 16 is preferably carried by I the face plate B, the upper end of the standard being angledo'ver to form a flange which may be riveted or soldered to the lace plate.

The lower end of the standard may also be angled as shown to form a hearing for. the spring pin 21 which projects through one or perforations 22, 23 ii the rock lever 15- and tends to hold the latter in the on or oil position ofthc switchuntil sinfi 'eret pressure has been exerted upon one or the other push buttons to force the pin back, whereupon the switch piece snaps -into or out of contact with the spring terminals 1213.

The side walls C of the casing ma he formed from a fiatbar of metal angled to the desired shape and provided with'lugs c which are let into corresponding recesses l; in the face plate. This wall portion C- may be seated in a marginal offset a in the base and the parts united by a screw 24, the shanl: of which passes through a hole in the base and engages a threaded perforation in the lower angled end of the standard.

1 claim as my invention:

l. A push switch having a standard a perforated rock lever pivoted thereon, a contact piece moving with said rock lever and a spring pin adapted to engage the perform tions in and temporarily detain said rock lever.

2. A push switch having'a standard, a perforated rock lever pivoted thereon, a con tact piece moving with said roclg lever and a spring pin carried by said standard adapt- 7 ed to engage the perforations in and temporarily detain said rock lever.

3. A push switch having a standard, a perforated rock lever pivoted thereon, a contact piece moving with said rock lever a spring pin adapted to engage the per-fora tions in and temporarily detain said roclr lever, said standard being angled at one end and perforated to form bearings for said pin, substantially as described.

4-. A push switch having a staudard,'a perforated rock lever pivoted thereon, a contact piece moving with said rock lever and a spring pin adapted to engage the perform tions in and temporarily detain said rock lever, together with means carried by said rock lever for limiting its oscillation.

5. A casing for push switch or the like comprising a metallic wall portion with positioning lugs, independent top and base, one of the latter having recesses corresponding to said lugs and the other being peripherally offset to receive the edges of said wall pen tion, in combination with a standard extend ing between said top and. base and carried by one of the latter and means in connection with the other for rigidly uniting said top and base to the wall, as described.

6. A casing for push switch having a Wall portion comprising a plate of metal an led to desired shape and provided with positioning lugs, independent base and top, one of the latter having recesses corresponding to said lugs, in combination with a standard 10 extending between said top base and carried by one of the latter and means in connection with the other for rigidly uniting said top and base to the Wall, as described.

In testimony whereof I have signed my name to this specification, in the presence of ].5

two subscribing witnesses.
